I played in HS, club play in college and local club until I put the racquet down about 10 years ago. Recently, I started playing again and I am really enjoying it. However, it is difficult to find willing partners and I would like to join a league so that I can get some good match experiences. How do I go about joining a league? Do I need to be a USTA member first? Do I just contact regional coordinators? Thanks for your help.
